The formats time forgot
Every era of the internet left orphaned videos behind. FLV from the Flash years — Flash was switched off in 2020. RM and RMVB from the RealPlayer age. WMV and ASF from old Windows. 3GP from pre-smartphone phones. Sorenson-encoded MOV from early QuickTime — whose Windows player was discontinued back in 2016. The files still sit on backup drives; the players are gone.
This tool carries the real FFmpeg engine with the original decoders for all of them — RealVideo, Cook audio, WMV3, Sorenson, Cinepak, Indeo and more — running entirely in your browser. Old family recordings and downloads from 2007 are exactly the files you don't want to hand to a random website, and here you don't.
Frequently asked questions
Which formats can it read?
FLV, RM, RMVB, WMV, ASF, 3GP/3G2, OGV, old MOV and AVI variants (Sorenson, Cinepak, Indeo, MS-MPEG4), MPEG-1/2, VOB and more — the classic decoders are built in.
Why MP4 as the output?
H.264 MP4 is the most universally playable format that exists: every phone, browser, TV and editor opens it. WebM is offered for those who prefer fully open formats.
My file failed to convert — why?
Very exotic codec variants and DRM-protected files may not decode. If a file fails, it is worth trying once more with the other output format — and know that nothing was uploaded either way.
